Preface The world is much concerned about meeting the food demand of emerging population in thecontextofvariousbioticandabioticstressesaffectingthegrowthoftheplants,yield,and sustainable agricultural development. Agricultural research to improve and sustain food production especially using beneficial plant–microbe interactions is gaining importance. ImportantresearchprotocolshavebeenpresentedinPlant-MicrobeInteractions:Laboratory Techniquesfor thebenefitofglobalresearchersandstudentcommunity. This manual comprises of 83 protocols given under five major sections: biological nitrogen fixation,mineralsolubilization and mobilization,abiotic stress management,bio- controlofplantpathogens,andbiologicalcontrolofinsectsandnematodes.Ingeneral,this manualcoversvariousprotocolsrelatingtoplant–microbeinteractionswiththepreparation of reagents and important instructions/special note relating to the practicals. We devoted much care to the preparation and compiling of each and every protocol provided in the manual. We strongly believe that the lab manual will meet the practical and research needs of postgraduate students, research scholars, postdoctoral fellows, and scientists as well as teachers from various fields, including pathology, microbiology, entomology, and agron- omy. We thank the Springer Publications for their support and cooperation for bringing outthislabmanualinanicemannerandontime.Wehighlyappreciateyourvaluableinputs andconcretesuggestionsfor theimprovementofthemanual.
